SHOE-LAST.

Specification of Letters Patent.

Patented July 1'7, 191W.

Original application filed July 11, 1916, Serial No. 108,597. Divided and this application filed September 30, 1916. Serial No. 123,066.

To all whom it may concern:

Be it known that 1, JOHN E. Hoornma citizen of the United States, residing at Louisville, in the county of Jeiferson and State of 'Kentucky, have invented certain new and useful Improvements in Shoe Lasts; and I. do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in shoe lasts and the principal object of the invention is to provide a last for holding shoe nails or tacks temporarily during the securing of the sole in place.

This application is a division of my copending application filed July 11,1916, Serial No. 108,597.

Another object of the invention is to provide a nail holder for shoe lasts consisting of a series of disks or plates having their faces resiliently held in contact and arranged with their edges disposed outwardly so that the point of a nail when driven through the sole of a shoe will enter the spaces between the disks thus forcing the same outwardly and causingsaid plates to frictionally engage the point-of the nail and hold the same against accidental movement.

With these and other objects in view the invention consists in the novel combination and arrangement of parts which will be fully set forth in the following specification and accompanying drawings, in which Figure 1 is a bottom plan view of a shoe last showing the same equipped with my improved tack holders.

Fig. 2 is a side view partly in section of Fig. 1.

Fig. 8 is a fragmentary plan View of a modified form of the device.

4c is a side view partly in section of Fig. 3.

5 is a sectional view through a fragment of the last showing the use of disks instead of plates.

Fig. 6is a fragmentary sectional view through the last showing a modified form of spring, and

Fig. 7 is a detail perspective view of a further modified form of holding element showing the plates secured adjacent their ends by rivets.

Referring to the drawings the numeral 1 designates the toe portion of the last while the numeral 2 designates the heel portion. In the form of the device illustrated in Figs. 1 and 2 the toe portion is provided with a cover plate 3 which covers the sole portion thereof, while the heel portion of the last is provided with a cover plate 4 covering the sole portion of the heel section. The toe and heel portions of the last are provided in their sole faces with recesses 5 which are adapted to receive the tack holding elements which will be more fully hereinafter described. Suitable openings 6 are formed in the plates 3 and 4c and are arranged directly over the recesses 5to admit the point of the shoe tacks when the same are driven in place.

In the modified form of the invention illustrated in Fig. 3 the sole portion instead of being covered with. an entire plate is only provided over each of the recesses with rabbeted portions 7 for the reception of the plates 8 which are formed with openings 9 through which the points of the shoe tacks project when they are driven in place to engage the holding element. In this form it will be seen that the plate 8 instead of covering the entire sole portion only covers the outer sides of the recesses 5 and tacks driven through the openings will enter the holding element as in the form illustrated in Figs. 1 and 2.

In the form of holding element illustrated in Figs. 1 to 4 inclusive, it will be seen that the same consists of a series of plates 10 having their edges preferably sharpenedand arranged with their faces in abutting engagement. These disks are resiliently held in such engagement by means of a substantially U-shaped spring 11 the arms 12 of which turn outwardly as illustrated in Figs. 2 and 4: and have their ends engaged against the end plates. It will thus be seen that when a shoe tack is driven in place the point will be guided between the plates so that the same will be forced outwardly against the tension of the spring 11 and thus the shoe tack will be firmly held in place and against accidental removal.

In the modified form of the invention illustrated in Fig. 5 it will be seen that disks 13 are used in connection with the spring 11 in place of the plates 10 as previously de scribed and like the plates 10 these disks are sharpened at their edges to provide guides ofjtlie plates 14 a pair of bowed springs 15 are provided and are arranged in such .a

position that their bowed surfaces engage the,,end walls of the recesses, while the ends of the same engage against the'end plates 14 jthus resiliently holding said plates in the properfpo sition. v I

Y In the modification illustrated in Fig. 7 it willb'e seen that instead of a plurality of substantially square plates a pluralityuof si'lbstantially rectangular plates 16 is prohaving theiradjaeent faces in abutting r p engagement and these plates 16 have their upper edges sharpened and are drilled near opposite ends to receive rivets ofbolts 17 It will thus be seen that the intermediate portions of said plates will be free tobow Q outwardlywhen a nail is driven between the same and thus the nail will beheld firmly in place. .-:It will be understood that thestructures, illustrated in Figs. 5, 6, and ,7 are to beletinto recesses formed inqthe sole p ortions of. the toe and heel portions of the last and it willbeunderstood that these recesses may. of any form and arranged to meet the-various requirements.

,.. l hilein the foregoing there has been shown and described the preferredembod i ment of this invention, it is to be understood thatsuchchanges maybe made in theeoinbination and arrangement of parts, as will fall within thespirit and scope of the invention as claimed;

' time this pa e m be maiied'fbr hat is claimed is 1. In a tack retaining unit, a plurality of plates, a U-shaped spring embracing said plates, the arms of the spring engaging the outer faces of the end plates and holding the adjacent faces of the intermediate plates in yieldable abutting engagement.

2. The combination with ,a shoe last hav ing a plurality of recesses in its sole portion, of a plurality of plates having their exposed edges sharpened seated within the recesses andbowed springs engaging the end walls of the recesses and the end plates to resiliently liold said plates in abutting engagement with each other. l

i 3 In a shoe last, abody, a metallic plate covering the sole portion of said body, said plate being provided with openings therein and tack clamping elements inserted in the body immediately beneath the openings, said elements consistin of aplurality of disks arranged in abutting engagement and springs to urge said disks toward each other.

4. In a slioe last, a body having recesses in the sole portion thereof, a metallic plate covering the sole portion of the body, said plate being provided with openings arrangedin alineinent with the recesses, said openings being-smaller than the recesses and adapted to receive shoe tacks, a plurality of disks located in the recesses in the body, the edges of the disks being curved to form guides for the shoenails to guard the ends thereof between thedisks and spring means for holding said disks in abutting engagementwith each other to clamp a shoe nail between the disks when the same is driven in place.
